The table below shows the height (in inches) and weight (in pounds)of eight basketball players.
Height=67, 69, 70, 72, 74, 78, 79 Weight=183, 201, 206, 240, 253, 255 what is the correlation of the set of data? Round your answer to the nearest thousandth.
d.0.981
3.The table below shows the average height of a species of tree (in feet) after a certain number of years.
Years=1, 2, 3, 4, 5, 6, 7, 8 Height=2.1, 3.2, 6.8, 7.3, 11.2, 12.6, 13.4, 15.9 about how tall would you expect one of these trees to be after 22 years?
c.44.25ft
4.You use a line of best fit for a set of data to make a prediction about an unknown value. The correlation coefficient for your data set is 0.984. How confident can you be that your predicted value will be reasonably close to the actual value?
c.I can be very confident; it will be close, but it probably won't be exact.

equivalent fractions are fractions which have the same value.
equivalent fractions all have the same simplified form
we can write equivalent fractions by multiplying both numerator and denominator by the same number. We can also write equivalent fractions by dividing both numerator and denominator by the same number
so 5/10
we can get the equivalent fractions by multiplying by a common number
when we multiply by 2
when we multiply by 3
when we multiply by 4
the three equivalent fractions are
10/20 , 15/30, 20/40
Answer:
x < 7
Step-by-step explanation:
First apply the -2 onto each term that it is being multiplied onto.
-2x + 6 > - 8
Now subtract six from both sides.
-2x > -14
Now divide by -2.
x < 7
<u>REMEMBER</u>
When doing greater than and less than equations like this, if you divide by a negative you must flip the greater than/less than.
